York City Police are looking for Juijuan Maurice Williams Sr., 34, of the 800 block of Wayne Ave., York.

York City Police are looking for a man who they say allegedly attacked his girlfriend — including head-butts and uppercut punches — to the point that she needed neck surgery, according to an arrest warrant.

The warrant charges Juijuan Maurice Williams Sr., 34, of the 800 block of Wayne Avenue, York, with one count each of aggravated assault, simple assault, recklessly endangering another person and terroristic threats.

As of Tuesday morning, Williams had not been arrested, according to online court dockets.

According to the warrant, on July 5, York City Police were sent to York Hospital to interview victim Ashley Nichole Beck, who was in the intensive care unit after having undergone neck surgery.

Beck said that prior to the alleged attack, she and her boyfriend, Williams, were at a friend's house in the 1100 block of East Market Street. About 7 p.m., Beck received a text from her ex-boyfriend, and Williams asked who it was. Beck, not wanting to lie to him, told him who had texted her, the warrant states.

"Williams became upset, grabbed Beck's cell phone then head butted her," according to the warrant. "Williams yelled at Beck, 'The only way out is in a coffin.'"

He then head-butted her again, which caused a "gaping wound on the top right part of Beck's head," according to the warrant.

"Beck started to black out as Williams gave two upper cut punches to Beck's left side of the jaw," the warrant states.

Beck was able to run away and call a family member to get a ride to York Hospital. Once there, Beck received neck surgery, as doctors fused two vertebra in her neck and placed five staples in her head where she had been head-butted, according to the warrant.
